TREATMENT AND PREVENTION OF DEFICIENCY DISORDERS
INTRODUCTION
-
Micronutrients (vitamins and minerals) are required in small amounts for:
- Growth and development
- Maintenance of health
- Disease prevention
-
Some nutrients are not synthesized in the body, so they must be obtained from diet.
-
Nutritional deficiency occurs when:
- Intake is inadequate
- Absorption is impaired
- Requirements are increased
-
Common causes:
- Poor diet
- Disease conditions
- Malabsorption
- Drug interference
GENERAL SYMPTOMS OF DEFICIENCY
- Pallor (pale skin)
- Fatigue and weakness
- Breathlessness
- Palpitations
- Dizziness or fainting
- Depression
- Tingling and numbness
- Hair loss
- Poor concentration
- Menstrual irregularities
- Constipation
- Sleep disturbances
1. PROTEIN DEFICIENCY DISORDERS
Protein-Energy Malnutrition (PEM)
Common in children (1–3 years), leading to:
- Growth retardation
- Increased morbidity and mortality
Causes:
- Inadequate diet (poverty, ignorance)
- Infections and parasitic diseases
A. KWASHIORKOR
- Caused by protein deficiency with adequate calories
Clinical Features:
- Edema (especially feet)
- Distended abdomen
- Fatty liver
- Dermatitis and skin depigmentation
- Hair thinning
- Irritability, anorexia
Management:
- Gradual protein supplementation
- Balanced diet
- Treat infections
B. MARASMUS
- Severe deficiency of protein + calories
Clinical Features:
- Severe wasting (emaciation)
- Loss of fat and muscle
- Loose skin folds
- Dry skin
- Irritability, hunger
Management:
- Gradual nutritional rehabilitation
- Treat dehydration, infections
- Correct electrolyte imbalance
C. CACHEXIA
- Wasting syndrome due to chronic diseases (e.g., cancer, AIDS)
Features:
- Weight loss
- Muscle atrophy
- Weakness
- Loss of appetite
Treatment:
- Nutritional support
- Appetite stimulants (e.g., corticosteroids)
- Treat underlying disease
2. VITAMIN DEFICIENCY DISORDERS
Classification
- Fat-soluble: A, D, E, K
- Water-soluble: B-complex, C
A. VITAMIN A DEFICIENCY
Functions:
- Vision
- Immunity
- Growth and development
Deficiency:
- Night blindness
- Xerophthalmia
- Keratomalacia
- Blindness
Management:
- Vitamin A-rich foods (carrot, spinach, liver)
- Supplementation
B. VITAMIN D DEFICIENCY
Functions:
- Calcium & phosphorus regulation
- Bone health
Deficiency:
- Rickets (children)
- Osteomalacia (adults)
Sources:
- Sunlight
- Fish, egg yolk, fortified milk
Management:
- Sun exposure
- Vitamin D supplementation
C. VITAMIN E DEFICIENCY
Functions:
- Antioxidant
- Protects cell membranes
Deficiency:
- Neuropathy
- Myopathy
- Hemolysis
Management:
- Dietary intake (nuts, oils, green vegetables)
- Supplements if needed
D. VITAMIN K DEFICIENCY
Function:
- Blood clotting
Deficiency:
- Bleeding disorders
- Easy bruising
Management:
- Green leafy vegetables
- Supplementation
E. VITAMIN B-COMPLEX DEFICIENCY
Includes:
- B1 (Thiamine) → Beriberi
- B2 (Riboflavin) → Cheilosis, glossitis
- B3 (Niacin) → Pellagra
- B9 (Folic acid) → Anemia, neural tube defects
- B12 → Megaloblastic anemia, neuropathy
Sources:
- Whole grains
- Meat, fish
- Legumes
Management:
- Balanced diet
- Supplementation
3. MINERAL DEFICIENCY DISORDERS
A. CALCIUM DEFICIENCY
- Causes: Poor intake, kidney disease
- Symptoms: Cramps, osteoporosis
B. IRON DEFICIENCY
- Leads to anemia
- Symptoms: Fatigue, weakness
C. MAGNESIUM DEFICIENCY
- Symptoms: Weakness, cramps, arrhythmias
D. POTASSIUM DEFICIENCY
- Causes: Vomiting, diuretics
- Symptoms: Muscle weakness, arrhythmia
E. ZINC DEFICIENCY
- Symptoms: Poor immunity, hair loss, delayed healing
TREATMENT OF DEFICIENCY DISORDERS
1. Dietary Modification
- Balanced diet with:
- Fruits and vegetables
- Whole grains
- Proteins (meat, eggs, pulses)
2. Supplementation
- Vitamins and minerals
- Combination therapy (e.g., calcium + vitamin D)
3. Treatment of Underlying Cause
- Infections
- Malabsorption disorders
- Medication adjustment
4. Emergency Treatment
- IV fluids and nutrients
- Hospitalization in severe cases
MALNUTRITION
Types:
-
Undernutrition
- Wasting, stunting, underweight
-
Overnutrition
- Obesity
CAUSES
- Poverty and food insecurity
- Malabsorption disorders
- Alcoholism
- Mental illness
- Poor mobility
SYMPTOMS
- Weight loss
- Fatigue
- Poor immunity
- Delayed wound healing
- Growth retardation in children
TREATMENT OF MALNUTRITION
- High-calorie, high-protein diet
- Nutritional supplements
- Tube feeding (if needed)
- IV nutrition (severe cases)
PREVENTION
-
Balanced diet including:
- Fruits and vegetables
- Cereals and grains
- Milk and dairy
- Protein sources
-
Health education
-
Food fortification
-
Regular health checkups
